Super Mario World: Uber Edition

My first uploaded hack. Also my first hack with its own overworld. Please comment on any bugs or issues to make my game better on DEMO V2.

Story: Bowser has kidnapped the princess! But this time he found a great new world.

My game is supposed to be a bit harder than the original. I did Ctrl + Del all the levels and worked with to make them original. The first castle is my hardest level in my first demo.
